Title: Production equipment of film
Inventor: NISHIDA TAKANORI
IPC: B29C41/34
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To prevent the poor molding at the edge of a film and an air trapping from developing and realize a stable molding by a method wherein the flow of air, which flows from nozzle edge part sides into the direction of a resin film, is controlled and straightened at the widthwise edge parts of the resin film in the nozzle. SOLUTION: The flow and amount of air, which flows from the edge part sides of a nozzle 1 into the direction of a resin film 2, are controlled with a flow straightening means 11 provided at the edge parts of the nozzle 1. Since the above flow and amount is controlled by the size of the flow straightening means 11, the nozzle 1 and the position of the flow straightening means to a gap between the nozzle 1 and the casting surface 5, a proper controlling can be realized by installing the flow straightening means having an optimum size at an optimum position. The inflowing air through the edge parts of the nozzle 1 largely affects the moldability of the edge of the resin film 2 and the air trapping between the resin film 2 and the casting surface 5. The proper controlling of the inflowing air flow brings the stable adhesion of the resin film 2 on the traveling casting surface 5.  Thus, the moldability of the edge part of the resin film 2 can be improved, the air trapping between the resin film 2 and the casting surface 5 can be prevented from developing and a favorable quality and stable molding can be realized.

Abstract: PURPOSE:To enable a III-V compound semiconductor layer having reduced distortion in lattices to be formed on an Si substrate, by forming an Si-Ge mixed crystal layer and a single crystal layer each having a thickness smaller than a predetermined value on the substrate such that they are interposed between the substrate and the compound semiconductor layer.

The GaAs single crystal layer is caused to epitaxially grow in vapor phase so as to form the compound semiconductor layer 3. According to this method, any distortion in lattices due to a difference in thermal expansion coefficiency between the Si substrate 1 and the compound semiconductor layer 3 can be absorbed.
